Fatigue fracture of pressing die of tablet press The punching die of the tablet press is a part of repeated motion, so the probability of fatigue fracture exists. Once the die breaks in the work, the consequence is very serious. Therefore, the fatigue fracture of the die should be strictly prevented. We know that the fatigue fracture of steel has a development process of crack formation, expansion and fracture, and the fatigue fracture formation stage generally accounts for 70%~80% of the fatigue life. Therefore, preventing the premature formation of fatigue crack is the key to improve fatigue fracture. Fatigue fracture is the part under the action of cyclic load, starting from some weak links, the weak links of the punching die is in the punch arc transition which is easy to produce stress concentration, to prevent the formation of fatigue crack, the first is the selection of the punching die, that is, the punch and the punch body of the arc can not be too small; Secondly, the r

Flowability of capsule filling material The fluidity of filling material also refers to the smoothness. The variety of filling material is often powder and granule, etc. The fluidity of filling material will directly affect the control of capsule loading accuracy. The Angle of recline, bulk density, particle size distribution and water content of powder or granule have direct influence on its fluidity. Generally speaking, when the filling powder or granules are piled up, the Angle of recline of granules is smaller than that of powder, so the flow of granules is good, and the filling precision of capsule filling is easy to control. Bulk density refers to the weight per unit volume of powder or granule. In the process of filling, the weight per unit volume is larger, and the fluidity is good. It is also easy to control the accuracy of capsule filling. On the contrary, the weight per unit volume is small, the fluidity is poor, and it is difficult to control the accuracy of capsule f

Tablet press selection basis According to the production process and quality requirements of drugs, the selection of tablet press is mainly from the following aspects: (1) According to the characteristics of powder and particle, choose the appropriate tablet press (mainly Chinese medicine or western medicine, the composition proportion of raw and auxiliary materials, etc.); (2) Determine the output of equipment according to capacity and reserved capacity; (3) select the appropriate charging system according to the existing process; (4) According to the production record and deviation, equipment maintenance frequency and equipment control points in the production process of the product in the past; (5) the operation is convenient, reliable, there is a necessary adjustment device. Such as mechanical regulating device, filling regulating device, pressure regulating device, speed regulating device, sheet thickness regulating device, etc. (6) The design of the tablet pr

Typing problem of blister packing machine Type individual font is not clear can use a wire brush to clean the font surface debris, change the font, or on the pressure plate on the heat insulation film or medical tape. If the type is not clear, adjust the preload bolt, but do not increase too much preload, otherwise the noise is very large and easy to fatigue damage, in the case of preload can not be increased, you can appropriately increase the temperature of 5-10 degrees. Typing position adjustment can realize the up and down position of the font by adjusting the up and down moving handle, while moving the typing bar to change the left and right position of the font.

The function of each structure of the tablet press The lower punch fastening ring is unified, which has the following functions There is no need to adjust the fixed ring of each punch separately. The punch replacement speed is fast and the parts need to be cleaned less. This structure makes the fastening resistance of each punch equal, no need to adjust again. Special sealing structure The window is sealed by the special dismountable structure and material for cleaning, which ensures that the machine pressing studio is completely sealed and the cross contamination caused by dust is eliminated. The screw hole of the punching table is closed, and the sealing ring covers the screw hole of the punching table, so as to prevent the powder from entering, and accordingly reduce the cleaning time. Working window frame structure in line with GMP requirements The four-sided window structure is composed of frameless double vacuum, the surface is smooth and easy to clean, and the st
